I have passed the cbse board exam in march 2013 with 62 marks in maths and 85 marks in physics and 82% overall. So my question is that If I give The improvement exam in both physics and maths and get 85 in maths but 80 in physics so which marks would be counted? Like it would be the best of both or only the new marks would be counted? Also which marks would be counted for jee mains 2014. And I heard somewhere that if I give improvement exam in only subject then I won't be eligible for jee advanced 2014 unless I give Improvement for all the subjects.
Any answer is welcome
I hope that these are not too many questions...
